We all have our own opinion of what the vocaloid's personalities are. but what about Gumi? My opinion is she's kinda like a house wife, hence the earphones. For Kaito, he's kinda like a doormat for the vocaloids. Meiko's an alcohalic that's hyper. Miku's a happy, gentle singer. Rin is a crazy girl who can be shy at times and Len is a protective big brother. These are my opinions though. Post down here what you think the personalities are.
